Charles H. Spurgeon on Psalms 106:30

Then stood up Phinehas, etc. Mark the mighty principle, which rolled like a torrent in the heart of Phinehas. The Spirit leaves it not obscure. The praise is this, "He was zealous for his God", Nu 25:13. He could not fold his arms, and see God's law insulted, his rule defied, his majesty and empire scorned. The servant's heart blazed in one blaze of godly indignation. He must be up to vindicate his Lord. His fervent love, his bold resolve, fear nothing in a righteous cause. The offending Zimri was a potent prince: nevertheless he spared him not. Believer, can you read this and feel no shame? Do your bold efforts testify your zeal? Sinners blaspheme God's name. Do you rebuke? His Sabbaths are profaned. Do you protest? False principles are current? Do you expose the counterfeits? Vice stalks in virtue's garb. Do you tear down the mask? Satan enthrals the world. Do you resist? Nay, rather are you not dozing unconcerned? Whether Christ's cause succeeds, or be cast down, you little care. If righteous zeal girded your loins, and braced your nerves, and moved the rudder of your heart, and swelled your sails of action, would God be so unknown, and blasphemy so daring? Mark, next, the zeal of Phinehas is sound minded. It is not as a courser without rein, a torrent unembanked, a hurricane let loose. Its steps are set in order's path. It executes God's own will in God's own way. The mandate says, let the offenders die. He aims a death blow, then, with obedient hand. The zeal, which heaven kindles, is always a submissive grace. Henry Law, in "Christ is All", 1858.
